DRIVING MECHANISM FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 608,008, dated July 26,1898.

Application filed May 28, 1897.

To all whom it may concern:

Be it known that I, CARL THEODOR GOTT- LIEB SOHNEIDEWIND, of the freecity of Hamburg, in the German Empire, have invented a new and usefulDriving Mechanism with Lever and Friction-Disk for Vehicles,Velocipedes, and the Like, of which the followingis a specification,reference being had therein to the accompanying drawings.

The object of the present invention consists of a new drivin g-gear forvehicles,velocipedes, and the like, and is suitable for driving by handor foot, so that persons who for some reason or other are unable to usetheir feet are able to drive this mechanism. This is in the first placeconsiderably facilitated by the fact that the mechanism is propelled bya simple up-and-down motion of one or more levers.

In the accompanying drawings, representing the new gear, Figure 1 is afront elevation; Fig. 2, a side elevation, and Figs. 3 to 8 areexplanatory figures.

Upon the axle a is a toothed wheel I). (See Figs. 3 and 4 in elevationand section.) This wheel I) is loose upon the spindle and is pro videdwith a projecting circular flange c, the inner surface of which isturned. The boss at is also turned smooth. Upon this boss a piece 6,Fig. 5 in elevation, is placed, which carries the pins f f, which arearranged at right angles thereto. Upon each of these pins I a clamp g g,respectively, (see Figs. 6 and 7,

elevation section,) is arranged, which are rounded off at their upperand lower ends and are slightly longer than the distance between the hub61 and the inner surface of 0. These clamps can turn freely toward oneside upon the pins ff without, however, being able to pass the hub.Finally, the lever h is revolubly arranged upon the hub and is alsoprovided with two perpendicular pins 1' 11, upon which a disk rests.These pins 2' i" pass right through the disk It and engage withcorresponding holes i i in the clamp-pieces g g, so that upon moving thelever h in a certain direction the clamppieces g g must turn upon thepins ff. these clamp-pieces are somewhat longer than the distancebetween the outer periphery of the hub 01 and the inner periphery of c.The

clamps are so supported upon the pins f f that upon pressing down thelever hthey are As already mentioned,

jammed between the hub 01 and projecting flange c, and the tooth-wheelbis thus forced to rotate in the same direction as the lever. Uponraising the lever the clamps are again freed and slide freely upontheperipheries of the projecting flange and the hub.

The projecting flange 0 can be replaced by an independent disk Z, asshown in Fig. 1, whereby the same is securely fastened to thetooth-whee1 b by the extension of the hub Z, as shown in Fig. 1. Fromthis arrangement it will be seen that by an alternate up-anddown motionof the lever a continuous rotation of the tooth-wheel would be obtained.

In order to raise the second lever upon the downward motion of thefirst, both levers are provided with a slot m, in which a rod n isguided, which has a boss at its middle and turns upon the spindle p. Itis by this arrangement that the above-mentioned end is obtained. I

The rotation of the tooth-wheel b can be transferred as desired-as, forinstance, on a bicycle-by the insertion of another toothwheel .9, Figs.1 and 2, which gears with the tooth-wheel b and is securely fastened tothe chain-wheel A, which latter transfers the motion to the hind wheelof the bicycle by means of the chain. With this arrangement alarger orsmaller gear can be obtained, according to desire, without the need orexercising of great trouble by changing the wheel 3.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-- A driving-gear for vehicles, velocipedes and the like,comprising a wheel having a circular flange and a hub, a piece rotatablymounted with respect to said wheel, a clamp pivoted to said piece andengaging at its outer and inner ends respectively with said flange andsaid hub, and a driving-lever carrying pins engaging with said clamp, soas to cause it to engage the flange and hub and rotate the wheel whenthe lever is moved in one direction, and to release the clamp from thewheel when the lever is moved in the other direction.

Inwitness whereof I have hereuntoset my hand in presence of twowitnesses;

CARL THEODOR GOTTLIEB SCHNEI DEWIND.
